属性层次模型在银行投资决策中的应用

属性层次分析AHM是1997年程乾生教授提出的,它不需要进行一致性检验,也不需要求特征向量,它比AHP更加简单易行.本文应用属性层次模型方法AHM建立模型来评价企业的优劣,从而帮助银行正确决策贷款的投放对象.     

对评价大学生身体成分方法的研究

为研究在校大学生身体成分测量的最佳方法,采用皮褶法、生物电阻抗法(BAI)、身体质量指数(BMI)、腰臀比(WHR)和身高标准体重法,分别对随机抽取的220名大学生进行身体成分测试,并进行相关分析。结果发现:1.BAI、皮褶法、BMI和WHR可用来测量和评价大学生的身体成分,但其准确性依次是BAI>皮褶法>BMI>WHR;2.《标准》中身高标准体重不能客观有效地评价身体成分,故建议选用体脂百分比。     

The effect of pedometer use on physical activity and body weight in obese women

Abstract

Physical activity and healthy eating are of the utmost importance in treatment of obesity. However obese generally tend to have a sedentary lifestyle. Walking is a form of physical activity that is both simple and can be performed by everyone, but it requires an objective measurement. Number of steps taken during tracking can be recorded with the pedometer, a device used to measure the level of physical activity. We aimed to investigate whether or not using pedometers as a motivational technique to increase the level of physical activity in obese women has an impact on weight loss. Eighty-four obese women who are similar age referring to Ataturk University Faculty of Medicine Healthy Living Clinic, Turkey were randomly divided into two groups. Intervention group were given pedometers, and control group were prescribed similar diet and physical activity with a three-month follow-up plan without pedometers. Mean weight in pedometer group initially was 88.9 ± 8.4 kg, which decreased to 80.2 ± 8.7 kg after the programme. Mean weight in control group was 86.1 ± 9.2 kg at the beginning, and it decreased to 84.7 ± 8.8 kg after three months. It was observed in pedometer group that the mean number of steps 8817 ± 2725 steps/day at the beginning increased to mean 9716 ± 2811 steps/day at the end of the study. Weight, body mass index, body fat percentage and waist circumference measurements decreased more greatly in the pedometer when compared to the control group (p < 0.001). Pedometers may be recommended to obese patients to monitor and increase the level of physical activity and to promote weight loss.     

基于G1赋权法的部队装备保障演练考核指标体系权重研究

制约部队装备保障演练考核成绩准确性的一个重要因素就是考核指标体系的权重设置能否突出演练考核目标--部队装备保障能力的检验.为此,文章结合装备保障演练的能力指标体系的设置,通过对权重分析方法的比较.提出了采用G1赋权法来设置考核指标体系的权重,详细阐述了G1赋权法的原理、步骤,并以保障能力考核指标为例说明其具体应用,为进一步进行演练考核成绩综合评定的研究打下了基础.

有氧健身操和力量训练对年轻超重和肥胖男性体能与血液改变的对比研究*

国内肥胖和超重现象日趋严重,运动减肥中常用的两种方法：有氧健身操和力量练习方法,这两种训练方式如何改变年轻超重和肥胖男性的身体形态和机能？文章试图来给予正在利用这两类运动方式健身和减肥的年轻超重或者肥胖者一些科学建议,从而能够根据自身身体状态和需求来科学健身。研究方法：9周训练时间,分3组平行进行,分别为有氧健身操组、力量训练组和对照组,训练一般选在下午5点进行,每次训练90min,5次/周。实验前后分别测试受试者的BMI,体脂率,最大摄氧量,耐力,握力和弹跳力,以及血清中的白细胞介素1β(IL-1β)和6(IL-6),以及肿瘤坏死因子α(TNF-α),并统计分析实验数据,t检验实验前后和组间的差异。实验结果：有氧健身操和力量训练都能减少年轻超重和肥胖男性的BMI和体脂率,并增加肌肉量、握力和弹跳力,但有氧健身操改善受训者的心肺功能（最大摄氧量和耐力）的能力要强于力量训练。对于血清中的致炎因子影响来说,两种不同的训练方式起着完全相反的作用：有氧健身操能够降低致炎因子水平（IL-1β,IL-6,TNF-α）,但是力量训练却使致炎因子的水平增加。结论：建议想增加肌肉量的年轻超重和肥胖男性在使用力量训练的同时,结合有氧健身操的锻炼方法,使身体逐渐恢复健康状态。     

Identifying motivators and barriers to older community-dwelling people participating in resistance training: A cross-sectional study

Participation rates of older people in resistance training (RT) are low despite increasing research showing many health benefits. To increase the number of older people participating in RT it is important to know what would motivate people to become involved, what motivates those who participate to continue, and the factors preventing many older people from commencing participation. To investigate these issues, a questionnaire was mailed to three groups of older people: (1) those receiving home care services, (2) members of a peak non-government seniors’ organisation and (3) those participating in a specific gym-based RT programme. In total, 1327 questionnaires were returned (response rate = 42.5%). To feel good physically and mentally were the main reasons motivating participation among all three groups, and falls prevention was identified as an important motivator for the home care respondents. Pain, injury and illness were the main barriers to participating, or continuing to participate. However, medical advice was a factor influencing participation commencement. The results suggest organisations providing RT programmes for older people should tailor the promotion and delivery of programmes to address key motivators and barriers specific to each group to increase the proportion of older people initiating and continuing to engage in RT.
